Departmental Reports

Auckland

This will be the first report for some time which has not been initiated by Bob Doran, who has finally retired as Head of Department after more than 11 years in this position. Bob was appropriately "farewelled" to a strategically chosen remote office on the first floor of our building at a well-attended function at the end of January. We think that he is one of the longest continuously serving HODs at Auckland, but he probably has some way to go to match Brian Cox's tenure at Otago! Bob has been a strong advocate for Computer Science at Auckland, and has made an immense contribution towards the growth and success of our Department. Many of his achievements were recalled at his farewell gathering. One not-so-serious recollection was the time he used, in a memo to a "competitor" department, the phrase "internecine cooperation", thinking it meant something like "interdepartmental", when actually it means "deadly, characterized by great slaughter" or "mutually destructive". Now also, of or pertaining to internal conflict in an organisation".

Bob handed over a very useful HOD "Resource Kit" to his successor (the undersigned). It included many practical aids such as scissors for "trimming departmental budgets", extra strength aspirin for "consumption after senate meetings", chocolate fish for the "staff bonus incentive scheme", jelly beans to "assist with accounting", and worry beads for "trying times". Certainly the new HOD is relying heavily on his advice as he comes to grips with the job.

We have had a busy start to the academic year with a rather unexpected 20% increase in student numbers at all levels. This has created pressure on all parts of our Department, particularly after a budget cut for 1997. Academic and resource planning is already underway for 1998 and beyond, so we hope this cutback will only be temporary. The University will undergo an academic audit in July, and the Department itself will be reviewed toward the end of the year, so there is more paper work to come.

Various research activities within the Department are flourishing, with a boost provided by the arrival of the new professors Reinhard Klette and Clark Thomborson in 1996. The Computing and Information Technology Research Group has been established under Reinhard's leadership at Tamaki with emphasis on the areas of computer vision, artificial intelligence, data communications, computer architecture and cryptology. Clark has recently visited most Computer Science departments as visiting lecturer and is busy establishing the area of computer performance analysis within the Department.

Among other highlights, the Centre for Discrete Mathematics and Theoretical Computer Science, a joint venture between Auckland and Waikato under the leadership of Cris Calude and Douglas Bridges, is flourishing. A most successful conference was held in December 1996, and another conference on "Unconventional Models of Computation" will be held in January 1998. The Hypermedia Unit, under the direction of Jennifer Lennon, has continued its contracted work with outside organisations such as the Museum of New Zealand and the National Library of New Zealand. Jennifer's multimedia and hypermedia systems paper continues to be the most popular at Stage 4 level, with an enrolment of over 70 students this year. John Hosking and Ric Mugridge have secured a TBG contract to develop software for the design of aluminium frames for the building industry.

Victoria

At the beginning of March, the Department of Computer Science at Victoria was merged with the Department of Mathematics and the Institute for Statistics and Operations Research to form the School of Mathematical and Computing Sciences. Professor Rob Goldblatt is the new head of the School. This change was part of the restructuring process at Victoria which has replaced departments by larger schools. The Department of Computer Science no longer exists as a department, but the Computer Science staff, research, and teaching will continue as a group within the new school. It is too early to identify the effects of the new structure, but the gains that we hope for will be increased cooperation, especially in terms of research, between the disciplines, and a reduced administrative load on staff.

Enrolments

Otago CS

Enrolments were up again in 1997 compared with 1996, though not as large an increase as last year. The department has effectively doubled in size over three years from 125 to an estimated 250 efts this year, when second semester enrolments are added. We have yet to analysis the pattern of enrolments, but suspect that we have obtained a slightly higher percentage of women in our first year classes. Our percentage of female students at higher levels is still very low. I am hoping that Clark Thomborson will follow up his seminar here, by seeking comment from each university to see if the same pattern is occuring at all universities. Has anyone got a percentage of female students anywhere near their University average?

Stephen MacDonell

Lincoln

Enrolments for the B.Appl.Comp. degree are up in 1997, but enrolments of students for other service courses are slightly down this year.

Elizabeth Post

Canterbury

At Canterbury enrolments in the mainstream first year computer science courses have jumped by about 30% after limitation of entry was removed this year. Stage two numbers are also up, but third and fourth year numbers are down. The financial pressures on students appears to be one of the reasons that students are leaving earlier.

Tim Bell

Victoria

Enrolments are significantly up in Computer Science at Victoria. Early figures (always over optimistic) shows a 24% increase in total computer science EFTS over the same time last year. There has been some growth at first year (on the order of 10%) in students doing our first course for majors. Our biggest growth is at second year, with our enrolments running on the order of 40% up on last year. Part of this is a result of offering our first year courses over the summer as four week, intensive courses. Third year has seen a smaller flow-through effect of last year's growth at second year, and our new graduate enrolments are up very significantly after a marked lull in 1996.

Peter Andreae

Massey

Enrolments for us are up. We have a pretty flat graduate enrolment but have made up numbers on new intake and especially in newly resident overseas students who need to update their qualifications by taking an accelerated diploma in CS.

Chris Jesshope

Waikato

Overall Computer Science EFTS are up by approximately 20% at Waikato. This in part reflects a dip experienced in 1996, and also the introduction of Summer School courses this year.

Student Programming Competition

The New Zealand Programming Contest is an Annual Event for Teams of three people from Polytechnics and Universities throughout New Zealand. There are three divisions Year1, Year2 and Year3+ which correspond to the years of programming experience of the team members.

The contestants are provided with a set of problems graded as 5 point, 20 point, 50 point and 150 point problems and have to collaborate using one PC between them to produce a program which will give the same output as the judge's program when run against a data file.

This years contest was run a little later in the year than is normally the case and entries were correspondingly down. There were twelve Auckland entries, two from Otago and one each from Waikato and Palmerston North.

The overall winners were the Megamagic Team from Auckland University with a huge score of 420 points. Second was a Stuart Inglis in a one man 'Team' from Waikato with 150 points.

The Manukau Institute of Technology team WTZ won the Year one division.

Events

Formal Methods Pacific '97
Wellington (Victoria) 9-11 July '97
This is an umbrella conference, incorporating the 6th Australasian Refinement Workshop and the 3rd New Zealand Formal Program Development Colloquium. The conference will provide a forum for discussion of current research on mathematically-based techniques for design and development of computer systems, and will feature speakers from New Zealand, Australia, UK, USA, France, Germany and Brazil. For details, contact Lindsay Groves (lindsay@mcs.vua.ac.nz) or see http://www.comp.vuw.ac.nz/FMP97/.

The Australasian Refinement Workshops (formerly the Australian Refinement Workshops) have been held every 12 to 18 months since 1991. The New Zealand Formal Program Development Colloquia have been run since 1994. Both workshops have aimed to facilitate discussion and advancement of current research by focussing on work in progress, and both have attracted many active researchers from within Australasia and abroad. The two will be run together as a combined workshop for the first time in 1997. In recognition of the quality of papers presented at recent workshops, we will be refereeing papers and publishing proceedings for FMP'97. We will, however, still aim to provide the opportunity for authors to present work in progress and to encourage active discussion. We especially wish to encourage post-graduate students to participate.

GeoComputation '97-9th Annual SIRC Colloquium
Dunedin (IS Otago) 26-29 August '97
The 2nd International Conference on GeoComputation is to be held in Dunedin from August 26 to 29 incorporating research relating to all aspects of computational geography, the convergence of computer science, geography, geomatics, information science, mathematics and statistics.

ENZCon'97
Auckland (Massey) 1-2 September '97
There is no theme for ENZCon'97, it is however a stock take of electronics research, education and industry in New Zealand. Papers can be of any type, eg: application, tutorial, poster, etc. ENZCon conferences consider papers for acceptance relating to electronics, mechatronics, robotics, and related physics, technology, and educational subjects. If uncertain as to appropriateness, please enquire or submit an abstract. A papers committee will moderate and review submitted abstracts. In the event of there being more acceptable papers submitted than can be presented in the time available, the Papers Committee will make a further selection. It is hoped to arrange prizes for the best paper and poster.

For more information see http://www.massey.ac.nz/~ENZCon97.

Australasian Computer Science Conference
Auckland (Auckland) 1999
The Australiasian Computer Science Conferences will be held in Auckland in early 1999. It was generally agreed by those at the conference just finished at Macquarie University in Sydney that the conference held in Christchurch in 1994 was the best ever. We plan to at least maintain that standard in Auckland in 1999.

From past experience, there will be at least four conferences held around that time. At Macquarie, they introduced the term "Australasian Computer Sciences Week" for the following 3 conferences held this year-

ACAC Australasian Computer Architecture ConferenceMonday, Tuesday
CATS Computing-Australasian Theory SymposiumMonday, Tuesday
ACSC Australasian Computer Science ConferenceWednesday-Friday

There is usually a Database conference as well, but it was cancelled in favour of an international Database Conference in Melbourne later this year. There is also talk of a possible conference on Logic Programming as well for 1999. Institutions near the conference venue are also encouraged to hold specialist seminars, workshops etc before or after the main conferences (this is how the Architecture Conference started). The time is not yet decided, but many Australians spoke in favour of the week before Australia day (18 - 22 January).

Please note that all conferences include the word "Australasian" in their titles. It is our responsibility to maintain sufficient New Zealand interest to justify retaining this title, instead of the previous "Australian". So please everybody prepare to submit lots of papers and then attend the conference. For 1997, papers were submitted as
NSW27
Vic23
Qld19
SA11
NZ10
WA4
Tas1
Other18

So our paper submission numbers are already well up among the Australian states, but on a population basis we could well double the number of submissions-how about it?

As preparation for the wonderful week in Auckland, you should consider attending the 1998 conference in Perth, 2-6 Feb 1998. (And of course submitting papers.) Perth is a very pleasant city, much less hectic than East Coast cities. (I spent about 3 months of my 1995 Study Leave there.) While West Australia is a VERY big place with lots of very interesting scenery further north, there is good sightseeing with day-trip distance of Perth. Train enthusiasts might like to consider too the "Indian-Pacific" train Sydney-Perth (or Adelaide-Perth), regarded as one of the world's best railway journeys, but ensure that you book well in advance. However you get there, it would be good to have plenty of New Zealanders there, preferably presenting LOTS of papers.

For information on the Perth conference see http://www.cs.uwa.edu.au/acsw98.
